Abstract
The utility model relates to the spine surgical operation field, especially is a centrum dynamic stabilizer which bearing t he load elastically in interspinous region, and decreasing the stress load of the intervertebral discs, comprises a H shape implantation material and a binding rope; the side face of the H shape implantation material is arranged with a binding rope through hole, and the binding rope is passing through the binding rope through hole. The dynamic centrum stabilizer will bear the load elastically in interspinous region, and will decrease the stress load of the intervertebral discs; at the same time makes spinous process up and down through the binding rope, and operated as a interspinous region and spinous ligament; limiting the excessive anteflexion of the spine, and rebuilding the spine rear tension band.
Description
Technical field
This utility model relates to field of spinal surgery, especially a kind of can be between spinous process load capacity flexibly, reduce the intervertebral dynamic stability device of the mechanical load of intervertebral disc.
Background technology
Intervertebral disc degeneration intervertebral foramina stenosis patient in the past, the treatment that generally do not operate in early days, the excessive heavy burden in patient Chang Yinxiao joint or canalis spinalis dynamic narrow and often need stand slight illness operates after the neural by the time obviously compressing again nerve reduced pressure.Not making internal fixation after some patient's decompression merges, the stress that this moment, little joint was subjected to is bigger because of the excision of intervertebral disc, and acceleration regression, intervertebral space narrows down very soon, the narrow once again pressuring nerve of intervertebral foramina, symptom all appears in these all changes once more after operation, need operation once more to do the fusion internal fixation when serious.Usually close on after the internal fixation fusion go up or next sections because need the activity of compensatory spinal column to strengthen, also quicken to degenerate, because close on the often very fast needs of sections surgical procedure once more after the fusion.
Summary of the invention
In order to overcome above-mentioned deficiency, for the surgeon provides a kind of early stage regression patient that is used for, intervertebral dynamic stability device that can mitigation symptoms.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of intervertebral dynamic stability device, comprise H shape implant and binding rope, and the side of H shape implant has binding rope through hole, and the binding rope passes binding rope through hole.H shape implant is stuck between the spinous process, by binding rope binding spinous process up and down, plays between similar sour jujube and the effect of supraspinal ligament.
Further, for the ease of reliably, to bind rope easily is bundled in up and down between the spinous process, one end of binding rope has a ring set, the other end of binding rope is fixed with a puncture hook, puncture hook on the binding rope is used for the binding rope is passed interspinal tissue, penetrates the ring set of binding rope then, and is fixing in the side knotting realization of ring set; The binding rope has two.
Further again, H shape implant comprises flexible liner and lining cloth, and lining cloth closely wraps up flexible liner.
The beneficial effects of the utility model are: intervertebral dynamic stability device can be between spinous process load capacity flexibly, can reduce the mechanical load of intervertebral disc, simultaneously by spinous process about the binding of binding rope, play between similar sour jujube and the effect of supraspinal ligament, the restriction spinal column is excessively anteflexion, has rebuild spinal column rear tension band, simultaneously because of having born the weight of health, little joint is rearranged and is reduced mechanical load, and the intervertebral foramina height also can recover.Therefore, intervertebral dynamic stability device is used for early stage regression patient, can mitigation symptoms, obviously need to postpone the time of decompression operation, also can adopt the treatment of intervertebral dynamic stability device in early days to closing on the sections syndrome after merging, postpone the time of fusion, as far as possible motion segments that keep more.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1.H shape implant, 2. binding rope, 3. ring set, 4. puncture hook.
The specific embodiment
A kind of intervertebral dynamic stability device as shown in Figure 1 comprises H shape implant 1 and binding rope 2, and H shape implant 1 comprises flexible liner and closely wraps up the lining cloth of flexible liner.The side of H shape implant 1 has binding rope through hole, and binding rope 2 passes binding rope through hole.H shape implant 1 is stuck in elastic load capacity between the spinous process, simultaneously by spinous process about 2 bindings of the binding rope on the H shape implant 1, binding rope 2 has two, one end of binding rope 2 has a ring set 3, the other end of binding rope 2 is fixed with a puncture hook 4, puncture hook 4 by a binding rope 2, to bind rope 2 is enclosed within on the upper aristate process, pass the ring set 3 of another root binding rope 2 then, in the binding of ring set 3 one sides knotting realization upper aristate process, in the same way with spinous process under another root binding rope 2 bindings.
Claims (4)
